Aaargh.. that was annoying... much searching on the net to work this one out.
No thanks to you lot though ;-)

theurl = 'http://www.somerestrictedserver.com'
passman = urllib2.HTTPPasswordMgr()     
passman.add_password(therealm, theurl, username, password)  

*won't* work.
theurl starts with the protocol http:// which isn't what HTTPPasswordMgr needs.

theurl = 'www.somerestrictedserver.com'

works...
